Background.
Switzerland’s Noè Ponti entered the event as the world record holder and favourite, having lowered the previous mark to 21.50 during the 2024 World Cup. Ponti swam under the old record four times across the three World Cup stops, including a 21.67 in Shanghai and 21.64 in Berlin. However, Canada’s Ilya Kharun had declared his intent to challenge the record and had shown strong form, including a 19.94 flat-start 50 free and a 22.28 personal best in the 50 fly. The Netherlands’ Nyls Korstanje became the second-fastest performer in history with a 21.74 in Singapore, after three runner-up finishes to Ponti. Returning finalists included Szebasztián Szabó of Hungary (21.86), Teong Tzen Wei of Singapore (22.11), Chad le Clos of South Africa, Dylan Carter of Trinidad and Tobago, Marius Kusch of Germany, and Daniel Zaitsev of Estonia. Australia’s Isaac Cooper showed consistent sub-22.5 form, while the USA’s Dare Rose and Michael Andrew, and Great Britain’s Jacob Peters (22.10), were also entered.
"SwimSwam" predicted Ponti would win, Kharun would place second, and Korstanje would place third.
